I have experience running Kubernetes clusters on Hetzner dedicated servers, as well as working with a range of fully or highly managed services like Aurora, S3, and ECS Fargate. From my experience, the cloud bill on Hetzner can sometimes be as low as 20% of an equivalent AWS bill. However, this cost advantage comes with significant trade-offs. On Kubernetes with Hetzner, we managed a Ceph cluster using NVMe storage,…

Is it just me or do the last 3 paragraphs feel like ChatGPT output?

Yeah, I was wondering the same thing.

This is definitely some ChatGPT output being posted here and your post history also has a lot of this "While X, Y also does Z. Y already overlaps with X" output.

I'd like to see your breakdowns as well, given that the cost difference between a 2 vCPU, 4GB configuration (as an example) and a similar configuration on AWS is priced much higher.

There's also https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... to reduce the operational burden that you speak of.

I've never operated a kubernetes cluster except for a toy dev cluster for reproducing support issues. One day it broke because of something to do with certificates (not that it was easy to determine the underlying problem). There was plenty of information online about which incantations were necessary to get it working again, but instead I nuked it from orbit and rebuilt the cluster. From then on I did this every few…

This.

I run BareMetalSavings.com[0], a toy for ballpark-estimating bare-metal/cloud savings, and the companies that have it hardest to move away from the cloud are those who are highly dependent on Kubernetes.

It's great for the devs but I wouldn't want to operate a cluster.

Isn't the point of ChatGPT to mimic sentences written by humans?

Kind of. But which humans? It's a bit like how the average person doesn't exist, except in the LLM world, now it does.

Can anybody speak to the pros and cons of Hetzner vs OVH? There ain't many large European cloud companies, and I would like to understand how they differentiate. Ionos is another European one. Currently, it looks like their cloud business is stagnating, though.

I'd say stay clear of Ionos. Bonkers first experience in the last two weeks. Graphical "Data center designer", no ability to open multiple tabs, instead always rerouting to the main landing page. Attached 3 IGWs to a box, all public IPs, GUI shows "no active firewall rules". IGW 1: 100% packet loss over 1 minute. IGW 2: 85% packet loss over 1 minute. IGW3: 95% packet loss over 1 minute. Turns out "no active Firewall…

It is not possible to configure the setup without the graphical interface?

Are there cloud providers you prefer?

As far as I see, no one is mentioning sustainability AKA environmental impact or 'green hosting' here. Don't you care about that? I believe that Hetzner data centers in Europe (Germany, Finland) are powered by green energy, but not the locations in US.

Data centers used 460 TWh, or about 2% of total worldwide electricity use, according to IEA in 2022.

In comparison, 30% of total energy (energy! Not electricity) goes to transport!

As another point of comparison, transport in Sweden in 2022 used 137 TWh [1]. So the same order of magnitude as total datacenter energy use.

And datacenters are powered by electricity which increases the chance that it comes from renewable energy. Conversely, the chance that diesel comes from a renewable source is zero.

So can we please stop talking about data center energy use? It’s a narrative that the media is currently pushing but as so many things it makes no sense. It’s not the thing we should be focusing on if we want to decrease fossil fuel use.

> Hetzner volumes are, in my experience, too slow for a production database. While you may in the past have had a good experience running customer-facing databases on AWS EBS, with Hetzner's volumes we were seeing >50ms of IOWAIT with very low IOPS. See https://github.com/rook/rook/issues/14999 for benchmarks.

I set up rook ceph on a talos k8s cluster (with vm volumes) and experienced similar low performance; however, I always thought that was because of the 1Gi vSwitch (i.e. networking problem)?! The SSD volumes were quite fast.
